EU cross-border data protection may be getting more tangled, not less

The European Commission's "one-stop shop" plan to streamline the way cross-border data protection issues are handled has apparently been big-footed -- and complicated -- by the EU's Council of Ministers. The Commission wants a European Data Protection Board to have authority to reconcile differences among countries' privacy regimes, but now the Council says other "concerned bodies" should be able to object to the board's decisions. The aim is to have one jurisdiction for companies like Google, who now find themselves fighting simultaneous, overlapping legal battles in multiple countries.

Facebook rewrote its "Community Standards" to say that photos of "fully exposed buttocks" were not permitted, while also prohibiting harassment, bullying and hate speech on the site.

Telcos bet that "made in Germany" sounds more secure

U.S. tech products and services have been viewed with suspicion by privacy-conscious users in Europe since revelations about National Security Agency snooping blew up in 2013, and now telecom operators see an opportunity to differentiate their products from competing U.S. offerings. On Sunday at the Cebit trade fair in Hanover, Vodafone and Deutsche Telekom were not so subtly highlighting the German credentials of new security products that they introduced.

Watch now

Jim Cramer, the fast-talking host of CNBC's Mad Money, got a shock when he took a call from "Tim in Cupertino" on the occasion of the show's 10th anniverary, and it turned out to be none other than the Apple CEO.
